    Abstract: Disclosed is a control system for a melting process in an electric arc furnace for melting a metallic material that minimizes desired process properties such as the melting time or the total power consumption of the melting process. The system includes a processing unit adapted for receiving or collecting measured data of at least one process variable, determining the current state of the process, performing an optimization of the melting process, determining a process input based on the result of the optimization, and controlling the melting process with the process input. A method is also presented herein.

    Abstract: The dual-function impeller can be rotated in molten metal in a direction of rotation, as part of a rotary injector. The impeller can have a body having an axis, a plurality of blades circumferentially interspaced around an axis, and an aperture coinciding with the axis. The blades having both a radially extending portion facing the direction of rotation and collectively generating a radial flow component upon said rotation, and a slanted portion also facing the direction of rotation, inclined relative to a radial plane, and collectively generating an axial flow component directed away from the rotary injector upon said rotation.
